what do you think is better for a coil gun with a 9cm coil, 15-17layers of 22gage wire?

560uf x 280v OR 330uf x 385v?

Also I could use 3 capacitors but only of one of the types above.

hey. that is a good question. I recently have been designing a coil gun but I'm not sure whats more important: voltage, or capacitance.

I read on spud tech voltage is more important because its more power and its on for a shorter amount of time

Voltage is most important. High voltage means high amps, which means a stronger magnetic field.

Don't bother operating at below about 300 volts, and the more you can get the better.

More Voltage = stronger field
More capacitance = longer lasting field.

Don't overcook it on the capacitance, because if the field lasts too long then power is lost.

But he does have a fairly long coil. I myself used 4 x 385V 3300uF and 2 x 450V 1500uF capacitors when I made mine.
